Document Summary

The figure shows three electric charges labeled q 1, q 2, q 3, and some electric field lines in the region surrounding the charges. Answer: q 1 is positive, q 2 is negative, q 3 is positive. 7. 50 cm long carries a charge density of. Find the magnitude and direction of the electric field this wire produces at a point. Part c. if the wire is now bent into a circle lying flat on the table, find the magnitude and direction of the electric field it produces at a point 4. 50 cm directly above its center. Part d. answer: electric field is directed upward. Positive charge q is distributed uniformly along the positive y- axis between y=0 and y=a. A negative point charge q lies on the positive x-axis, a distance x from the origin. Calculate the x-component of the electric field produced by the charge distribution q at points on the positive x-axis.
